Ford F-150 (2004-2008) :: 2006 5.4L - Have Spark And Fuel But No Start?
Aug 6, 2012
I have 06 F150 5.4L with a no start condition. The truck comes from another shop with no improvement. This is whats done so far, replaced plugs, checked the fuel control module 100% ok, we have fuel pressure at the rail, we have injector pulse ( niod light ), we have spark and we have a good battery. We tore down the timing cover because of the sound of the engine turning over like it was out of time when cranking.
We did find a tensioner totally destroyed so we replaced the timing as put it back together and replaced the oil pressure switch because we get this "low oil pressure" in the info center every time, we also get gray/black puffs of smoke out the tailpipe when turning over. So to sum it up we have spark, fuel, and battery and still nothing! We even flashed the ECU and still no fire/no start.

I have rough idle problem after changing spark plugs, fuel filter and battery. There was no rough idle problem before this work was done. What could be wrong. Once the speed is above 20 mph it seem to run fine but at stops it vibrates and seem like it may stall!

I have a 2006 Fx4 with 60,000 miles. I wanted to change the spark plugs myself yet I can't seem to find were they are in the engine, I know how to take them out but I don't know how to get to them.

I am a newbie here, and also a new owner of a 2006 F150 XLT 4X4 with the 5.4 engine. It has 68K miles on it and looks to have been well cared for. I have a couple questions. First the truck is runnig great, no problems. I have read the threads regarding the spark plug issues and was looking for an opinion about changing them. Should I wait until I have problems, or due to the age of the truck, should I go ahead and attempt it soon? Also, I would like to find a used cap for the bed. I have the 6.5 bed, and wondered what range of years would work with my truck.

Brought a 2006 f350 6.0 from the action and knowing it was damaged from the frame, i went ahead and brought a another f350 6.0 2005 from someone around town, the last owner is calming the truck was stole, and most of the engine was stole, and the windows where damage. ( I just wanted to buy the truck for the body so i can transfer the engine to this one! ) but instead of switching the engine, me and my dad went ahead and only put the missing parts back onto the engine....
I can tell the last owner wasn't telling the truth, and me and my dad where thinking the last owner made up his own story about the truck being stole !! I did a vin check and noting came up about having a bad history!!!!!!!!! I'm thinking something went bad in the truck, and the last owner did his own fault story... Anyways!!!
we finally put everything back in place, and the truck cranks, but does NOT start!! and also has no spark. sometimes it sounds like it does wanna start!! we check the fuel, and wires, oil, fuel filer! everything good, but the truck has no spark, and where not sure if thats the problem. and also switch out the Crank sensor. Still no luck!!
And also there is smoke when we crank. battery are good too, and even left the truck 28 hours on the wire to head up the engine!!

Right now I am seeing roughly 41 MPG and that is after changing the spark plugs with brand new NGK Iridium's, Air intake filter and did an oil change since it was due for one. I have driven the car roughly 2,500 miles since all of this stuff was done and it just seemed to continue to drop to the 41 MPG mark.
What I have noticed though is that when the motor turns off it shudders and the when it restarts while the car is in park the car will roll back and forth slightly. I have also noticed that the car seems to struggle to get up to the posted speed while climbing an incline and also while the car idles in park or at a complete stop there seems to be a bit of a miss fire. Could that be caused by a bad coil? Because I have tried everything short of taking it to the dealer which I really do not want to do again and be told there is nothing wrong with it when I know there is.

Ok new issue that started yesterday only get it at idle. Runs great above idle no real power loss or change in fuel econ. Haven't really had a chance to test much. I was thinking maybe a injector issue but I don't know

I am working on a 2006 (production date 05/06) F150 quad cab 4x4 lariat with the 5.4 3V. I replaced all the plugs last week(and only 3 broke off) replaced the air filter and standard tune-up issues. Now when it starts up it will get a faint scent of fuel inside of the passenger compartment.
I have checked all of the fuel rail connections and the fuel injector seals for any leakage, Checked for any vacuum leaks, Checked for exhaust leaks, Double checked all electrical connectors. Everything that I have checked is as it should be with no sign of leakage or malfunction.
I can't find any source of the smell under the hood or under the truck. Thought maybe a fuel injector o-ring but can find no evidence to support removing the fuel rail. (leakage) Kinda at a loss here. Getting ready to go to lunch and start back afterwards.

Sons 94 ranger 4.0 4x4 Auto 185k got him to work yesterday but would not start to bring him home. No spark, checked with timing light, and no fuel pressure. Searched and read alot of tips from Pawpaw so I tried a few things with no luck. Swapped the relays around, inspected coil pack and plugs. CEL was not on and goes out while cranking. I have a OBD scan tool but this truck must be too old or I need finding plug. Crank sensor maybe?

I have a 2006 4.6L that's hard to start when it's relatively cold outside.
Normally, when it's warm outside, I can barely bump the starter, and it starts right up. But when it's cold outside, it usually takes 3 or 4 2-3 seconds of cranking before it starts. Even then, it has a really rough "about to die" idle, until about 10-15 seconds, and then it idles without a problem. Once it's running, it runs great.
It has 79k miles on it, and all I've done to it is put in a throttle body spacer, and a K&N filter. I've read a few posts from people that have had similar issues, that had K&N filters, but their problems have been more consistent. Mine only seems to happen when it's first started.
As far as I know, the plugs have never been changed, as with the COPs. I've heard about a vacuum line running to the throttle body may be the culprit, but haven't been able to find any more details on that, like where the line runs to, possible replacement part number for it, etc.

After replacing the intake manifold gasket for the second time, the truck would not start. Thought for sure it was my putting the distributor in wrong. After reviewing the forums, I am sure it is installed correctly. I have spark but no start. Engine cranks over nicely, but acts like it needs fuel. I hooked up a fuel gauge, turned on the key and get 56PSI. Lower than the 60 required. The pressure then slowly goes to 50 PSI. I pinched off the return hose and had the same readings. Pretty sure I need to replace the fuel pump. Is there anything else I need to check. I replaced the fuel pump a couple years ago with a Delphi unit. Maybe this is just a weak link for these trucks. My truck has a little over 100,000 miles on it.

I have a perplexing problem and I'm at wits end trying to figure it out. I have an 03 GTI 1.8t 20th. The car has been running great until today when I replaced a few bolts with the front bumper and replaced a motor mount bolt on the passenger side mount. Everything was great until I did the work on it. I figured I had bumped the cam position sensor so I swapped it out for a new one and nothing still. I have verified I have spark and I definitely have fuel as it keeps drenching the spark plugs. I have cleaned the spark plugs and tried starting only for the car to violently sputter and misfire. No codes are being recorded and nothing else has been touched.

Freshly rebuilt 2.8 V6
Car turns over but is not getting spark or fuel. The timing is good (checked multiple times, and I have done numerous TBs on these engines). Compression is good.
The car has sat for ~2 months. It broke the timing belt (and bent or broke multiple valves), so I know it had both spark and fuel before this.
I have gone through and double checked every connection and everything is connected and seated properly. I used a stethoscope to listen to the injectors and there is no click during cranking, and using an extra plug I checked spark and there is none. I also hooked up my inductive timing light and it doesn't sense a spark.
I have VAG-COM and there are no fault codes. I have checked all fuses and they are good. If I do the tests on VAG-COM I can make the injectors cycle, but they don't cycle when cranking. I tested the crank position sensor (and tried a new one) and it tested good (and the new one made no difference). Using VAG-COM, I confirmed that it does sense the engine RPM when cranking. The battery voltage stays above 12V during cranking as well.
A couple other tidbits of info:
The fuel pump does work (and comes on when cranking... confirmed by disconnecting the hose and pumping fuel into a can)
When cranking for a few seconds, the display says STOP and flashes the oil light (I'm assuming because it is cranking at such low RPM)
The Check engine light and EPC light come on when the key is put in the on position and turn off during cranking (like they should)
The immobilizer light comes on for a few seconds as well, but it doesn't flash like it would if it was immobilizing the engine.
After looking at wiring diagrams, it appears that the ignition coils and the fuel injectors both run off of the same relay, but I am unsure which one or even if I am right about that. But assuming I am correct about that, wouldn't the injectors not fire during the test if that was bad?

I have an 06 F-150 4x4 with the 5.4L Flex Fuel V-8. The truck has 133,000 miles on it. This morning, the truck was very hard to start. It took me 4-5 times of cranking the engine for 30 seconds or more before it started. Once it starts, it idles fine. Out on the road, the engine cuts out and the truck bucks pretty hard. The truck doesn't die, and the issue is intermittent. I changed the fuel filter less that 10,000 miles ago. The Check Engine Light has NOT come on. What could my problem be?
